Description
    Template for use with dynamic code generation of a source.
    The hook functions take the following arguments:

    \verbatim
    codeCorrect
    (
        GeometricField<Type, fvPatchField, volMesh>& fld
    )

    codeAddSup
    (
        fvMatrix<Type}>& eqn,
        const label fieldi
    )

    codeConstrain
    (
        fvMatrix<Type>& eqn,
        const label fieldi
    )
    \endverbatim

    where :
        fieldi is the index in the fields entry
        eqn is the fvMatrix
